Event handling in Visual C++ uses the Unified Event Model, which allows you to use the same programming model for event handling in all types of classes in Visual C++:

• Native C++ classes (C++ classes that do not implement COM objects).
• COM classes (C++ classes that implement COM objects, typically using ATL classes or the coclass attribute).
• Managed classes (C++ classes declared with the __gc keyword or by declaration in a managed context).
